As much as we love each and every episode of Real Housewives of Beverly Hills, it's safe to assume that most people's favorite part of the season is the always-tense reunion. Speaking of which, the cast has just filmed the Season 4 reunion, and they have been sharing their thoughts about it on Twitter.

The cast gathered with Andy Cohen to film the Season 4 reunion on February 7, and it sounds like it was a long day. "I'm exhausted!" Brandi tweets in the wee hours of February 8. "I want my mommy, my daddy and my ... Gaygent— good night."

When a Twitter follower asks Kyle Richards if she is "mentally exhausted" after the taping, Kyle responds, "yess."

However, Yolanda Foster seems to feel that the reunion went well, all things considered. "❤️The truth was prevailed, some mistakes acknowledged & apologies were made! #RHOBHReunion #Happytomoveon," she tweets.

And here's what host Andy Cohen tweeted in the middle of filming it: "Still shooting #RHOBHReunion — all I can say is I would've made a damn good therapist :-)"

Afterward, he writes, "Oh LORD, we JUST wrapped #RHOBHReunion — it is a DOOZY. very emotional."
